4 Claims. (Cl. 46-205) The present invention relates. to a toy and I more particularly to a pull toy in the form of a helicopter, the blades of which are rotated by the, movement 'of -the carrying wheels when the toy is pulled along a'iiooring.

plastic material. The movable parts of the toy comprise a .member forming helicopter blades and which member is :journaled for rotation in the fuselageofthehelicopter' to simulate the action of this type of airplane. The helicopter blades are operatively connected to the supporting wheels of the'helicopter so as to be driven thereby asthe toy is pulled" and moves alon and on a floor..

tionallyengaged by the driving disc ll to be rotated thereby and correspondingly rotate the shaft 28 which is journaled in the boss ll moulded inthe upper member" of the fuselage.

These elements-arelfinecessarily of such construction that-theyi: V V in one, piecefrom'; plastic material. The present inventionztherefor'e,fcontemplates the provision of a method anufacturing such operative eiements' from parts-"that may be molded from a plasticnlaterlal and assembling them in the toy as units.

These and otherv and further objects of the present invention wiltbe clear from the following description and the drawings appended thereto in which Fig. 1 is a plan view of a pull toy helicopter according to our invention; a

Fig. 2 is a section on the line 2-2 of Fig. 1; Fig. 3 is a section on the line 3-4 of Fig. 1; Fig. 4 is an exploded sectional -view of the parts which are assembled to form: the helicopter blade and its frictional driving member, the axle, supporting wheel and blade driving mem- Referring now to the drawings, the elements of the toy helicopter are formed from a plastic: -material which is molded into the desired form. It will of course be understood that the various elements of the helicopter are molded by conventional dies, which form ent invention.

helicopter blade [0 is provided with engaged by the driving axis IS on which the disc H carried on the the floor or support on which it is carried, the

no part of the 'pres-.

disc l2 which is otfbe ordinarily molded helicopter supporting wheels l8 and 20 are mounted. As the helicopter the disc I which extends through the-opening 24 of the under member 26 of The driven disc l2 extending axle 28 of the blades i0 is fricthe fuselage. down from the construct '2'. Each shaft 42 unitary member comprising, the helicopter blade 10 and frictionally driven disc i2. It would similarly be extremely dlmcult and costly, if at all plastic materiala unipossible, to mould from a tary structure comprising the 'toy carrying wheel: I! and 20 and the frictional driving member I s In order to form these members from parts that may each be molded from a single die, we the blades ill from a member having the shaft 28 from the end of which there extends a shaft 34 of reduced diameter. The axleor shaft 28 is inserted into the opening in the boss 30 to extend into the interior 36 of the upper. section 32 of the fuselage. The upwardly extending sleeve 28 of the driven disc is then arranged .on the shaft 34 against the shoulders 40 and cemented thereto by any suitable means.

Each element of the blade assembly may thus be molded from a single die and when assembledin the upper section 32 of the fuselage can,-

not be removed therefrom, the blades l0 and shaft 28 serving as stop members against the boss 30.

Each wheel l8 and. is likewise made in a single die and has extending therefrom an axle forming element 39 from each of which the reduced shaft 42 extends. The driving disc I4 is made in the same die that the driven disc I2 is made and also has a sleeve 14 extending therefrom.

- The wheels and disc driving member are as-;

semble'd on the lower section 20 of the fuselage by inserting a shaft 39 in one-of the carrying members 48 extending down from the section is inserted in the sleeve 44 with'the disc ll extending up through the opening 22 and the sleeve 44 and pins 42 cemented together, the shoulders-43 bearing against the driving disc ii and its .sleeve '44. The thus formed wheel, axle and driving disc assembly unit is held in place by the wheels I8 and 20 which serve as stops against the downwardly extending carrying members 46. v

The lower and upper sections 26 and 32 are then cemented together to form the completed helicopter toy.

- It will be understood that, if desired, the drivtrated.

It will be apparent that each of the elements comprising our toy helicopter may be molded in a corresponding die from a plastic material and readily assembled together to form a comparatively inexpensive helicopter pull to). the blades of which will be rotated upon moving the toy on a supporting surface.

We claim:

1. In a pull toy in the form of a helicopter, the

material, a blade member, an upper fuselage section, a boss in the upper fuselage section, said blade member having a, shaft Journaled in the boss and extending into the interior of the upper fuselage member, for receiving and securing therein the said shaft on the blade member extending in the interior of the upper fuselage section, a lower fuselage sectionhaving carryin means extending downward therefrom and having an opening in the floor thereof, a wheel on each side of the fuselage and having a shaft iournaled in the carrying means and a driving means having a sleeve, said members instead of the frictional discs illusparts of which are each molded from a plastic driving means being open to receive and secure therein at each side' thereof each shaft on the wheels, said driving means extending through the in the opening to form a wheel and axle assembly a driven means having a sleeve,

having an intermediate driving means mounted thereon.

4. The toy of claim 3 said driving means comprising a disc having a sleeve extending therefrom.
